RF Measurement has been an expensive work so far the
cost of measuring instruments are concerned.
Although, the other project, PM2, is hot favorite
among radio amateurs for RF Measurement, I wanted something smaller
& more economical for measurement of RF Signals.
In this project a quality Double Sided PTH Board is
used measuring only 3cm x 10cm in size.
Same good old AD8307 from Analog
Devices is used (DIP Package) for basic RF measurement up to
500MHZ from -70dbm to +10dbm.
However instead of using a PIC and LCD, I am
using a simple LM3914 Bar Graph IC for display of db levels.
